Hi, How can I get details on the wt input in pwm generator block of simscape when the mode of operation is chosen as synchronized. I am currently modeling a pwm controlled inverter for bldc motor control. Any help is highly appreciated.
When set to Synchronized, the carrier signal is synchronized to an external reference signal (input wt) and the carrier frequenc...

I need to implement the state space model of Brushless DC Motor without simscape or any other advanced Toolbox(prerequisite). I have been stuck for a long time just at state space implementation because my state matrix is dependent on the angle.
The BLDC model is nonlinear; therefore, a Linear Time Invariant (LTI) state space model would not be that suitable. If you reall...
